Application filed January 19, 1925, Serial No.-3,264, and in Germany February 11, 1924.

My invention relates to aircraft lighter The disposable lift of an airship comprises ballast and paying load as pasfuel, crew,

sengers, mail and freight. The same airship may be used for long trips carrying only a few passengers but taking much fuel, while it may as well serve for shorter trips where less fuel will be necessary but more passengers may be taken. It would be an enormous additional weight to the airship if rooms for all paying load that might possible ,be taken on shorter trips would be provided in the airship structure from the beginning, and the weight of such partitions for rooms would unnecessarily cut down the lift disposable forpaying load on long trips where part of such arrangement would not be made use of but carried along as dead weight.

Therefore, according to my invention, I provide for partitions which are not a part of the original ship structure but which may be put up if necessary and which may be re-' moved again afterwards. Such partitions may be arranged in any place of the lighter than air ship, but I prefer to provide for them in connection with the usual gangway structure of the airship where it is especially advantageous. to have the necessary additional rooms, as the gangway will naturally provide for access to them.

Having given a general explanation of my now want to point it out in detail referrin to the drawing in which an example embodying my invention is shown.

Fig. 1 is a diagrammatical cross section of the gangway of an airship to which the partitions for an additional room have been fastened (seen in the direction of arrow A 'in Fig. 2). Fig. 2 is the corresponding side elevation in part, and Fig. 3 is the ground plan corresponding to Fig. 1.

The longitudinal girders of the gangway are designated by the letter (1 and the cross girders are shown at g. The inner edge of the floor a of the additional room is con:

'nected with the lower girder d of the gang, way bymeans of hinges 1). Its outer edge is supported by tension members 0 which are fastened to the upper longitudinal gangway girder d". These tension members may be provided with t-urnbuckles e for the purpose of accurate adjustment. Other tension members 0 are provided for rigidly staying the floor a by connecting; its outer edge with girder d. These tension members may be arranged so as to intersect and they also may have turnbuckles. i l

I prefer to have thefloor a constructed as one undivided rigidfstructure. -The walls 7 confining the additional room may easily be put up resting on: the floor platform a and will be connected with the same, with each other and possibly with the upper gangway girder d in any suitable and well-known manner.

It isto be seen that the'installation of floor a as well as its removal will take only a. very short time. For many purposes it will be satisfactory to have only floor a put up, without walls 7, for example, if add tional space for baggage or mail only is wanted. But it will also be easy to add the Walls 7 in case passenger cabins or quarters for the crew should be wanting. For longer trips, fuel tanks, for example, may be substituted collapsible structure. Occasionall it may \also be useful to take the parts 0 the collapsible structure with the ship, but in folded up state, so as to be able to'put the structure up while on the trip if so desired.

many variations will occur tov those skilled in the art. What I claim is: '1. In an airship, a rigid structure, a floor platform, means for detachably connecting one edge of said platform to'f said structure I- do not intend to limit myself to the details described or shown in the drawing, as

for the e and'tension members at the ,other edge of said platform adapted to def-alchably support same from said structure.

2. In-an'airship, a rigid'structure, a floor platform, means for detachably connecting one edge of said platform to said structure, and tension members at the other edge of said platform adapted to detachably support Same from said structure and to rigidly secure same in relation to said structure.

In testimony whereof I atfix my signature.
